Omni-Blade

The Omni-Blade (Shown right on Shepard's left arm) is an omni tool highlighted by an orange glow. Like other omni-tools, the omni-blade is a hologram projected over most characters arm. It is similar to other omni-tools, however, the omni-blade can be used to attack enemies. When in close combat you will be able to pierce through enemy armor and deal a large amount of damage, if not taking them down in a single blow.

The omni-blade has different animations when used by different classes such as a stabbing motion for Soldier class to a double swipe for Sentinel class.
